-' To all whom may c oncernii Be it known thatI, BENJAMIN C. 'SMITH,

I Fig.2 is a similar view of amodification.

Fig. 3 is a relatively enlarged view f 'i certain parts shown in Fig 2.

lrepresents a case or contalner which is preferably cylindrical in formand which may be provided with. aremovable .cap 2' so fitted thereto as to form an air tight joint at the upper end; 3 is a pipe leading from the.

oppositeendand having delivery branches 4,5,- 6. The pipe lleads to-thefront pivot of a load carrying spring 7 The pipe 5-.1eads to the shac {1 ing an internal diameter or bore say-of ap proximately three .siXty-fonrths of an inch.

and heavy pressure must be appliedto the surface of the grease to force it through the delivery pipes. The delivery 'pipesyby reason of their small bore, permit the grease When the parts being. lubricated are movin'g',.the' movement tends to rub-off in the form of a thin film a portion of the grease should be properly looped andmade flexible.

I at the exit end of the delivery pipe, this'being continued so long as said movement continues. ,By preference Ipro'vrde 'a'connec'ti'n'g pipe 9 between the combustion chamber of'the cylinder 10 and the interior of the case 1; Inithe forni shown, the 1 cylinder '10 represents conventionally the cylinderbf an internal combustion engines 11 is a check valvein the-pipe line, 9 whichgoperates to hold the pressure in the case 1 during the exhaust" and suction stroke of. the engine;

piston. "One substantialadvanta e is derived by providing pressure on t e grease in the case 1 from the engine oilinderpto wit, pressure generationstopsw t the stopa pins for said spring. The pipe 6 leads towhat is conventionally illustrated as a steering knuckle 8.. The de-' livery pipes 4,.5 and 6 .are verysmallhavping of the motor, and'starts with the starting thereof;

In- Fig; 2 I have shown the grease delivery pipe as leading direct "from the case '1 to outlets conveniently arranged between the spring-- leaves of the spring 7. In'this case the pipe isindicated'at l2 and the outlets at 13l3. As shown in Fig. 3 by dptted lines, the outlets 13- 13 screw 1nt0- a hole'in the top leaf while the balance vof the .leaveswith the exception of the bottom leaf are drilled so that grease maybe forced: betweeneacjh of the spring leaves to keep Y them properly lubricated at all times.)-

While I haveshown in the drawings the deliverypipes as leading to only certain parts to be lubricated; it will he understood that similar pipes may be led to any part of the vehicle where wear is likely to occur and where lubrication is desired;- By this simple means, the lubricant may be put in in bulk at a single 'sou-rce and delivered therefrom automatically every part of the mechanism associated with-the vehicle where lubrication-is desired. ltf-vvi'll be understood that the delivery pipes rililst necessarily be so small as to effectively resist the toorapid' flow of lubricant therethrough." While it is impossible to v specify actlythe internal diameter of the delivery pipes;- it is manifest thatthey must be 'sufliciently small to offer such resistance to -the flow of the relatively thick lubricant so that the same will not be wasted. I have found that by. this arrangement no controlling valve mechanism whatever is needed in said delivery P P It will be understood'of course that when the pipe is associated with partsth'atjpartake of movement, such as example the middle portion of a spring 7, the delivery pipe I have-found that copper tubing has sufficient flexibllity for this purpose. What I claim 'is:. 7

1. A lubricating system for automobiles and thedike-comprising, a container for holding a supply of relatively thick lubricant, such as grease, .with means for making the same air tight at one enidra lubricant outlet at' the otherend and a" delivery pipe leading therefrom"to .its destination, the bore ofsaid delivery pipe being sufliciently small to prevent the. passage of said lubri- 'cant excepting.. under heavypressure, a d; means fonapplying heavy pressure with the cylinder at the end opposite the delivery mechanical part to be lubricated, a container for holding a .Supply of relatively thick lubricant, Such 'as grease,nmeans forener-" atmg heavy pressure 111 one end of sa1 container, a delivery pipe leading from said container te the "mechanical part to be lubricated, the bore of said pipe being sufficiently small t'o prevent theflow of such lubricant therethrough excepting under high pressure, an internal combustion engme'for said vehiale, and a' pipe connection from the combustion' chamber. of Said eIlglIIQ to said ta1ner,- to furnish sald pressure B NJAMIN 0.
